Abstract: 837,379. Sintering ores. METALLGESELLSCHAFT A.G. Oct. 8, 1958 [Nov 5, 1957], No. 32162/58. Class 82(1) In a process for carrying out endothermic reactions on a sintering apparatus with simultaneous employment of solid fuel and hot gases, at least two different streams of hot gases are drawn through a bed of material to be reacted, a first stream being drawn from an ignition hood, and a second stream being drawn through the material, adjacent the first stream, the second stream having a temperature lower than that of the first stream, the temperatures of the streams being such that the molten zone within the bed is maintained as thin as possible. In an example a mixture of roasted pyrites, blast furnace dust, magnetite concentrates, pelletized mill dust, purple ferric oxide ore, recycled material and coke fines is sintered on a continuous machine as shown in Fig. 2, a first stream of gas at a temperature of about 1000‹C. being drawn through the bed from hood 4. A second stream of gas at about 800‹C. from hood 5 prevents the formation of a melting zone b (Fig. 2a), of undesirable thickness. One or more further streams of gas at a higher temperature, e.g. a stream of gas at 900‹C. from hood 6, may be drawn through the bed.

Title: Aircraft with lift rotors arranged symmetrically on each side of  the fuselage
IPC: B64C29/00
Filed: 1970-07-02
Abstract: 1311774 Aircraft with lift rotors VEREINIGTE FLUGTECHNISCHE WERKEFOKKER GmbH 2 July 1970 [3 July 1969] 32247/70 Heading B7W [Also in Division F2] An aircraft has lift rotors 12 mounted symmetrically on each side of the fuselage 10, each rotor having blades including bodies of revolution 14 rotatable about their own axes 15 for producing lift by the Magnus effect, axial flow turbines for rotating them and means for directing the exhaust gases from the turbines to nozzles so as to rotate the rotor about its axis 16 by jet reaction. Within each blade is a shaft 21 about which the rotatable body 14 may rotate on bearings 32 arranged on turbine stages 23, and rigid with the end of the shaft is an end piece 22 having outlet nozzles 24. Gases, preferably from an engine used for forward propulsion of the aircraft, pass, as indicated by arrows 29, through the turbines 23 so as to rotate the bodies 14 and then emerge through the nozzles 24 so as to rotate the rotor. If the engine delivers hot and relatively cool gas streams the hot gas can be passed through shaft 21, which is made hollow, to rotate the rotor, while the cool gas passes through the turbines to rotate the bodies 14. A suitable bearing for mounting the rotatable blades is described (Fig. 5, not shown). In a modification, Fig. 6, the body 14, mounted on shaft 43, tapers towards its outer end, and gases, after passing through turbine 50, are deflected by plate 46 and are emitted through nozzles 45, inboard of the body 14. The rotors are used for providing lift only, and may be locked with the blades parallel to the direction of travel when the aircraft is cruising. In each embodiment vanes 52 in the nozzles are adjustable, and may be fully closed during cruising.

Title: A periodicity analyser for a quasi-periodic signal
IPC: G10L25/90
Filed: 1970-07-06
Abstract: 1,264,060. Pitch extractors. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 6 July, 1970 [9 July, 1969], No. 32717/70. Heading H4R. [Also in Division G4] In a fundamental frequency detector, particularly for use as a pitch frequency detector in a vocoder, the signal is converted to a number of pulses whose positions correspond to the peaks of the input signal, and the pulse signal is applied to a cascade arrangement of period filters having mutually different characteristic time durations. As described a speech signal is rectified and passed through a low pass filter before feeding a peak enhancer in which peaks obtained by peak rectification are added to the enhancer input signal to provide a signal with very pronounced peaks which are used to trigger a pulse generator to provide a train of pulses each occurring at the positions of the peaks of the enhanced signals. The pulse signals are fed to a cascade arrangement of period filters each of which comprises a monostable circuit triggered by the positive edge of an incoming pulse signal, and which resets a predetermined time after the most recent positive edge. The period filters are connected so that each has a period before reset which is a predetermined amount, e.g. 10%, greater than the preceding filter. In operation the first stage which is not reset provides an indication of the fundamental frequency of the signal input. In order to distinguish sub periods in the input signal from the main periods, a pulse stretcher is provided in respect of each period filter stage. The pulse stretcher comprises a circuit element similar to a period filter connected by an "AND" gate to the output of the respective period filter stage and to the output of the preceding filter stage. The stretcher is operated if a starting signal, i.e. a positive-going edge, is available from the previous filter stage while a positive signal is maintained in the associated filter stage. The output from the stretcher may then be arranged to operate lamps or a digital device to indicate the period established. A further development, Fig. 6, includes an additional "OR" gate, e.g. 644, arranged between the period filter stages, e.g. 44, 46, which prevents gaps in the operation of the stretchers when the fundamental frequency is slowly increasing. In addition the stretcher is fed via an OR gate, e.g. 442, with signals from the stretchers of preceding, related, and following stages, and the output signal is derived from the stretcher output via an "AND" gate, e.g. 345, fed with the output of the related stretcher and the inverted output of the succeeding stretcher, in order to ensure that only one output terminal is active at any one time.

Abstract: 765,649. Door-operating apparatus; hinges. DEWHURST & PARTNER, Ltd., DEWHURST, M., WARD, A. J. C., and MINNS, G. E. Dec. 21, 1953 [Dec. 24, 1952], No. 32727/52. Classes 65 (1) and 65 (2). Door operating apparatus.-A lift door is operated by an hydraulic ram 2, Fig. 5, to the cylinder of which fluid is supplied by a pump 4 for opening the door; when the door reaches the open position, fluid escapes through an axial passage and radial port 21 in the ram 2 and a passage 22 to the reservoir, the pump continuing to run to hold the door open, and when the pump is shut off the cylinder is opened to exhaust through a valve 15 to allow the door to close. In the arrangement shown, the valve is spring-pressed to the position in which exhaust is allowed through passage 13; it is urged to close this passage when the pump is running, as shown, by fluid pressure acting on a piston 8, and fluid passes to the ram through an axial and radial passage in the piston and valve, any excess pressure being relieved by a valve 26. The reservoir, ram cylinder, valve, pump, and an electric motor for driving the pump preferably form a unit mounted on the top of the lift cage, and the pump is of the positive-displacement kind; the ram actuates a rack engaging a pinion on a shaft which carries an arm connected to the door by a link formed with offset end portions pivoted to the arm and the door respectively so that the link can lie in the same plane as the arm. Both arm and link are adjustable in effective length. The door is closed by a weight attached to it by a cable. The arm and link may be on dead-centre when the door is open, starting from this position being assisted by a spring acting on the pivot between these two members (see below); they are not on dead-centre in the closed position, to allow of opening by hand. In a lift having an attendant, the crank may move beyond deadcentre in the open position, the door being held there by its closing weight and the pump motor being switched off; the closing movement is then started by a device operated by the attendant. Hinges.-The arm 30, Fig. 2, has a forked member 44 adjustably fixed to its end by a sleeve, and the link 31 has a double offset end portion 32 embracing the member 44 and connected to it by a pivot pin 34. A torsion spring surrounds the pivot-pin, and is held stressed by a pin 46 on the member 44 engaged by both ends of the spring, being further stressed when the arm and link come into line, by a pin 48 on the part 32 engaging one end 47 of the spring. Specification 765,650 is referred to.

Abstract: 1456089 Cameras SEIKO KOKI KK 24 July 1974 [24 Aug 1973] 32730/74 Heading G2A A camera has means for generating a number of pulses dependant on subject brightness, a counter 6 for counting the pulses, means for controlling the shutter time in accordance with the count and a shutter time indicator 5A, 5B, 5C actuated in dependence on the count; the indicator comprising trigger pulse generators 5A connected to selected stages (e.g. F3 and F4) of the counter 6 to produce a number of trigger pulses representing the count in the counter 6, a counter 5B for counting the trigger pulses and indicators, e.g. light emitting diodes Ll, L2 for indicating the trigger pulse count and thus the exposure time. As shown, if counter 6 counts four pulses its output 93 turns on transistors Tl, T2, T3 to generate a trigger pulse which via a flip-flop T7, T8 energizes a diode L1 to indicate a speed of 1/1000 second. Similarly if counter 6 counts eight pulses diode L1 is turned off and L1 on to indicate a speed of 1/500 second. In the preferred embodiment, counter 6 is reversed when the shutter opens and when the count has returned to zero the shutter is closed. To enable the indicator to indicate the shutter speed during this reversal, diodes, Dl, D3 maintain the trigger pulse generators T1-3 and T4-6 in their triggered state once they have been triggered.
